BOTTLE-CAP" REMOVE-R.

Application filedOctobr 23, 1924, Serial Kb.745,'486. Renewed February5, 1927.

The invention-relates to improvements in bottle cap removers andparticularly to a device for removing the customary cardboard caputilized on bottles such as milk and cream bottles, and an Object of theinvention is to, provide a simply constructed, inexpensive and durabledevice which can be,

readily manipulated by the operator and which will effectively removethe cap and without disturbing the contents of the bottle.

A further object is to construct the device so that no skill or care isrequired in operating it to remove the cap.

lVith the above more important objects in view the invention consistsessentially in the arrangement and construction of parts hereinaftermore particularly described, reference being had to the accompanyingdrawing in which:

Fig. 1 is a vertical sectional view centrally through the appliance asit appears applied on the bottle cap and in the initial position, thespear point being shown in side elevat-ion.

Fig. 2 is a view similar to Figure 1 showing the position taken by theparts after the spear point has been depressed to pass through the cap.

Fig. 3 is a view similar to Figure 2, but

showing the device in the position which it occupies when one is readyto withdraw the caught cap.

Fig. .4: is a horizontal sectional view at tflc' Figure 1.

Fig. 5 is a perspective View of the bottle cap remover.

In the drawing like characters of reference indicate corresponding partsin the several figures.

It is well known that cardboard caps are utilized for sealing bottlessuch as milk bottles and that difliculty is experienced in removing thecaps as they are tightly seated in the neck of the bottle and liedirectly over the liquid contained therein. The present device isprovided to permit one to easily remove the cap and without disturbingthe contents of the bottle and it is constructed as hereinafterdescribed.

A rigid hearing or base plate 1 is provided, this being disc-shaped andhaving a diameter somewhat less than the open end 2 of the bottle neck3. As is customary the bottle neck is provided with an internal seat 55a on which the bottle cap 5 rests and the plate 1 is adapted to take a.position directly on'top of the cap and'with the edges thereof justnicely clear of the neck of the bottle to allow of the ready removal orinsertion of the plate. I

The platev is provided with -a central centrally positioned opening 7which receiv es' slidably aplunger or shank 8,-the lower end of which isfitted with a spear point 9 which is, in the present instance,cone-shaped. The spear point isnormally positioned between the upperpart of the bridge and the cap, and the cap is provided with a centrallypositioned opening 10 which is large enough to permit of the passagethrough the plate, of the spear point. The upward travel of the spearpoint is limited by the spear point striking the bridge. The upper endof the shank terminates in a finger ring 11 and between the ring and theplate I locate a coil spring 12, the lower end of which encircles thebridge. This spring normally holds the spear point in its uppermostposition or as best shown in Figure 1.

When it is desired to remove the bottle cap 5, one places the plate 1 ontop of the cap and it will be here observed that the outer edge of theplate overlies the seat 4' above the cap so that any down pressure onthe plate is transmitted directly through the cap to the seat. The platehaving been put in place, one then forces the shank downwardly to passthe spear point through the cap, the position of the parts thenappearing as shown in Figure 2. This being accomplished, one releasesthe plunger and the spring draws the spear point upwardly, the cap beingthen caught between the enlarged end of the cone-shaped point and theplate. One then lifts the device and the cap is withdrawn therewith Thewithdrawn cap can be readily removed from the spear point subsequently.

til)

bridge 6 and the bridge is provided with a foot portions arranged atopposite sides of said openings, vertical portlons extending upwardlyfrom the inner ends of said foot the opening in the bridge member andterminating at its lower end in a spear point larger than said lastnamed opening but smaller than the opening in the base plate.

whereby upr-rard movement of the spear point is limited by contact withthe horizontal portion of the bridge member said spear point being ofsuch length as to project but slightly below the base plate whendisposed in raised position between the vertical portions of the bridgemember, a

handle formed at the upper end of said shank and a spring confinedbetween the handle and the foot portions of the bridge member andencircling the vertical portions of the bridgeinember so asto be therebyheld in concentric relation with the shank, said spring serving tonormally hold the shank in elevated position with the spear pointengaging the horizontal portion of the bridge member.
